EXTENSION-TABLE.

SPECIFICATION forming part'of Letters Patent N o. 711,042, dated October14, 1902.

Application led April 23. 1902. Serial No. 104,238. (No model.)

To n/ZZ 11:71pm, it may cm1/cern:

Be it known that I, SAMUEL DUsnNBnRY, a citizen of the United States,residing at San Francisco, in the county of San Francisco and State ofCalifornia, have invented certain new and useful Improvements inExtension- Tables, of which the following is a specification.

My invention relates to improvements in extension-tables, the object ofmy invention being to provide an extension'table of which the parts tobe inserted in the top to provide a greater length of table-top shall be.con tained within the table itself, which can-be operated with ease andwithout undue exertion on the part of the operator, and which shallpresent a scarcely perceptible difference in appearance from an ordinaryextension dining-table.

My invention therefore resides in the novel construction, combination,and arrangement of parts for the above ends, hereinafter fullyspecified, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a perspective view of myimproved table in its closed position.` Fig. 2 is a similar view withone side removed to show the slats rolled up. Fig. 3 is a perspectiveview of my improved table extended. Fig. 4 is an under plan view of thetable extended. Fig. 5 is a transverse vertical section on the line A Aof Fig. 4. Fig. 6 is a longitudinal vertical section on the line B B ofFig. 4, showing one end Wholly drawn out and the other end partly drawnout. Fig. 7 is a perspective view of the hinge-plate for attaching theouter terminal slat to the end portion of the table. Fig. S is avertical section showing the position of the end slat with reference tothev end of the table when folded up. Fig. 9 is a perspective viewshowing the pusher-strip for pushing up the center slats into positionwhen the table is fully extended. Fig. 10 is a lon gitudinal sectionillustrating this feature.

Referring to the drawings, 1 represents the end sections of my improvedextension-table mounted upon the corner-legs 2. The central legs 3 ofthe table support a cross-bar 4, upon which is supported a center piece5, having side beams 6, joined by the end beams 7. Said end beams arerecessed, as shown at 8,

to allow of a telescopic connection between said end beams and the endsections of the table, said connection comprising sections 9, eachhaving side bars 10, having tongues 11, moving in corresponding groovesin the side bars of the next succeeding section and connected bytransverse bars 12, which transverse bars abut against the similar bars12 of the next section, and thus act as stops. The tops of said sidebars 10 are flush with the top of the side beams G of the center piece,and are thus in contact with the under surface of the top of the table.center piece are cut through, as shown at 13 in Fig. 3, to form paths,each turning upon itself to permit the slats 14 to move therein. Saidslats 14 are connected with each other by means of the hinge-plates 15,each hinge-plate being attached to the bottom of a slat through twoholes 16 and the hinge-plates being hinged together, as shown at 17, andthe terminal hinge-plates at each end are connected with plates 1S,which have longitudinal slots 19 therein,through which pass screws20,screwed into the under surface of the end section 1 of the table-top.When it is desired to extend the table, the ends 0f the top are pulledapart and the plates 18 are pushed towardthe middle, so as to permit ofthe hinge connection between said plates and the hinge-plates l5 of thefirst slats to come underneath the ends of the table-top, therebypermitting the slats to swing upward level with the table-top.

The hinge-plates 15 have also formed in the center thereof apertures 23,which are engaged by pins 24 on al roller 25, constituting asprocketwheel,so that when said roller is turned the slats are movedoutward, thereby extending the table. In order to prevent the slatsrising up from the top of the table, each Slat is provided with adownward and lateral extension 26, which passes underneath a guide 27 onthe side-of the center section. Vhen the slats have been moved as farvaspossible by means of the pins or sprocket-Wheel engaging the aperturesin the hingeplates,there will be still one or two end slats hanging downin the middle of the table. To move said slats up 'into position levelwith the rest of thetable, there are provided on the top of yeach sideof the center piece lifter-plates 2S,

which slide inward and are moved by means of pins 29, being guided intheir movement by studs 30, working in slots 3l in said guides. They arethus pushed forward over the openings in the side beams of the centerpiece made to receive the slats and cover said openings, lifting theslats into position. To close the table, the rollers are rotated in theopposite direction, and to assist in withdrawing said slats there areprovided tapes 32, which are connected at-one end to the end slat whichcomes to the center of the table, said tapes passing over idle rollers33 and thence passing to the rollers 25. Thus by revolving said latterrollers in the opposite direction the slats are positively drawn back bymeans of said tapes 32.

I claiml. In an extension-top table, the combination of the endsections, the center piece,each side of which has two tracks, each trackbeing cnt out in said side and extending from the center of the table inthe direction of the end, a shaft extending through a side of the table,whereby it can be operated from the outside, slats connected with theend sections, and an operative connection between said shaft and saidslats to be moved by the rotation of the shaft, substantially asdescribed.

2. In an extension-table, the combination of the end sections, thecenter piece, each side of which has two tracks, each track being cutout in said side and extending from the center of the table in thedirection of the end, a roller extending across the table, and having asprocket-wheel thereon, and slats having secured on the under sidethereof a sprocket-chain engaging said sprocketwheel, substantially asdescribed.

3. In an extension-table, the combination of the end section, the centerpiece having its sides cut out to form tracks for the slats of thetable, slats connected together to move in said tracks, a rollerprovided with means for engaging said slats to positively move the samein said tracks, an idle roller, and a tape attached at one end to thefirst roller and passing around said idle roller and attached at theother end to the innermost slat on the side of the table, substantiallyas described.

4. In an extension-table, the combination of the end sections, thecenter piece, the slats movable on said center piece, means for movingsaid slats, hinges by which said slats are connected together, andasliding hinge-plate attached to the under side-of the end section atthe inner end thereof, and attached to the hinge on the terminal slat,said sliding hingeplate being suitably guided to slide n nder the end ofthe end section, substantially as described.

5. In an extension-table, the combination of the end sect-ions, thecenter piece having guides, the slats attached to each other and alsoattached to said end pieces, and moving in `guides in the center piece,andthe pusherstrips for pushing up the innermost slats of the two serieslevel with the other slats, substantially as described.

In witness whereof I have hereunto set my hand in the presence of twosubscribing witnesses.

SAMUEL DUSENBERY.
